OpenBSD Errata: January 11th, 2021 (nd6)

Errata patches for the kernel have been released for OpenBSD 6.7 and 6.8.

When an NDP entry is invalidated the associated layer 2 address is not
invalidated.

Binary updates for the amd64, i386, and arm64 platforms are available via
the syspatch utility. Source code patches can be found on the respective
errata page:

  https://www.openbsd.org/errata67.html
  https://www.openbsd.org/errata68.html

As these affect the kernel, a reboot will be needed after patching.
